DRAFT-BIGGING.

Tc all whom 'it may concern:

Be it known that l, JOHN F. OCoNNon, a citizen of the United States, residing in Chicago, in the county of Cook and State of y illinois, have invented a new and useful Improvement in Draft-Rigging, of which the following is a s ecilication.

My invention re ates to draft rigging for railway cars.

The object of my invention is to provide a draft rigging of a strong, simple, efiicient and durable construction, and which will be adapted for use upon single center sill cars without the necessity of cutting or weakening the center' sill.

My invention, consists, in connwtion with a single center sill car, of a stations l fy niaft lug orstop member secured te the center sill below the same, and movable draft niembers, followers and cushioning devices also mounted below the center sill, transfer' levers pivotally connected to said fulcrum plates or members, one on each side of the center' sill, and connected at their lower ends to the movable draft members, and a pair of upper movable draft members connected to the draw head and fitting one on each side of the center sill and connected to the upper ends of the transfer levers. My invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing, forming a part of this speciiication, Figure l is a side elevation, partly in vertical section, of a single center sill car draft rigging embodying my invention; Fig. 2 is a plan view, partly in horizontal section; Fig. 3 is a vertical' 40 cross section on line 3--3 of Fig. l and Fi ..4 is a vertical cross section on line L.t4 of i 1; Fig. 5 is a detail longitudinal sectiona view of the frictional cushioning devices.

In the drawing A-represents the center sill of a car of the kind having a single center sill, A1 the front or end sill and A2 the carry iron.

B is the4 draw headof the car coupler and B1 is a pair of upper draft members pivotally connected thereto at their front ends by upright pivot pins l) and fitting one on each side of t e single center sill A.

C C are a pair of fulcrun'i plates, rigidly and 'lirrnly secured to the single center sill A.,

one en each side t -ercof by rivets c. To these fulcrum plates a pair of upright transfer levers D D are pivotally connected by horizontal pivot pins (Z. The fulcrum plates C have sockets or upright slots c1 to receive the transfer levers D. The upper pair of draft members B1 are pivotally connected at their rear ends to the upper ends of the 'transfer levers D by horizontal pivot pins d1.

F F are the lower pair of movable draft members7 one fitting on each side of the draft rigging cushioning devices and each preferably of a semi-cylindric shape on their inner faces or sides to embrace the cushioning devices, 'the saine being pivotally connected by lio ontal pivot pins d2 with the upr tran levers l). Each of the lower movable draft members F is furnished with pocket or shouldered recess to ernbrace and engage the ends of the followers E. The draft rigging cushioning devices preferably consist n a spring or springs Cr q, a longitudinally movable friction shell H, friction blocks lill, and wedg or spreader block H2 in the fric f n shell and interposed between the spr G and the front follower Fi. A preli nary compression block or follower li)2 is preferably interposed between tlie rear follower E and. the rear end of the spring G.

lil is the stationary draft lug or stop meinbei rigidly and firmly secured to the single center sill A, preferably by rivets K1 extend- I ing through the lower llange c, of the center sill A., and through the flanges 'E2 of the stop member l. The stop member FQ is furnished iifithsteps er shoulders l@ l@ engaging the fcllowers E. The movable draft members F have ,shouldersfly'1 which serve for lin ting the movement of tli.efollowers and the compression olY the springs. The

central draft lug cr stop member l is also provided 'with a bottoni webfih.7 to receive and support the lower pair cf movable draft members F F and the cushioning devices embraced thereby. '.llie draft members F have suliicient play between the bottom web or guide K7 upon which the saine rest and the .lower flange a to accommodate the Islight swinging movement of the lower ends of the transfer levers D, it being understcod in this connection thatA the total movement of the draw-bar and of the draft members F is ordinarily' only about three inches.

I claim:

l, In a single center sill car draft rigging, the combination with the single center Vsill and draw head, of a draft lug memberl secured to said center sill belenv the same and furnished with stops for the followers to abut against, a pair of fuleruni plates secured to said center sill, one on each side thereof, a

pair of transfer levers pivotally connected to said fulcrum plates, a pair of movable draft members, one on each side of the plate, and connecting the draw head with the upper ends of said transfer levers, a ltm'fer pair of movable draft members coimectcd to the lower ends of said transfer plates and furnished with means for engaging` the followers at their ends, and followers and cushioning devices, substantially as specified.

' 2. In a single center sill car draft rigging, the combination with followers and enshioning devices'below the center sill, a pair of movable draft members fitting astride the center sill, and connecting means betr-.reen said movable draft members and the cushioning devices below the center sill, substantially as specified.

3. In a single center sill car, the combination with center sill and draw head, of movable draft members fitting astride the center sill, a draft lug member below the center sill, movable draft members below the center sill fitting astride said draft lng member', and connecting means between the upper and. lower movable draft members, substantially as specified.

4. In a single center sill draft rigging, the

combination with cushining devices, followers, stops and a draft member belowv the center sill, of a dran.' head and a pair of movable draft members above the cushioning devices and fitting ast-ride the center sill, and connecting means between said first mentioned and last mentioned. movable draft members, substantially specified.

5. In a single center sill draft rigging, the combination with the center sill, of fulcrum plates secured thereto, transfer' levers, a draw-r head and connections between the dran head and said transfer' levers, saidv connections 'litting astride the center sill, substantiallr as specified.

6. The combination with a center sill, cfa draft lug or stop member secured thereto belov.' the same, provided with stops and a lower web for the draft appliances to rest upon, a pair of movable draft members fitting astride said top member, substantially as specified.

7. The combination with a center sill, of draft mechanism below the center sill, a dranr head and movable draft members connected to the draw head and fitting one on each side of the center sill and having a pivotal` connection with the dra-v: head, and a pair of connecting levers between said draft mein-l bers and said draft mechanism below the center sill, substantially as specified.
